Paper Title
Assessment and Design Options of Thailand’s Feed-in Policies

Thailand has been one of the successful countries in promoting electricity generation from renewable energy sources (RES-E). The main mechanism is driven by feed-in policies. These programs were firstly implemented as fixed premium tariffs, so-called Adder scheme, in 2006. Since the policy implementation, it effectively stimulates the national renewable electricity market. Renewable energy uses for electricity, in Thailand, increase steadily over the last decade. The proportion of the RES-E generation increased from 4.3% in 2007 to 9.9% in 2014. The policies have now been in the transition stage from Adder to fixed feed-in tariff (or FIT) schemes. The fixed FITs of rooftop solar power were initially promulgated in 2013. Afterward, the FITs of other RES-E generations were then applied in 2015. From the ten-year experiences, the policy implementation has achieved in attracting many private RES-E generators. The investors, however, still face the main problems of uncertainty and discontinuity. The several policy options are then discussed.
